STRAUSS MOQRING MAST FOR AIRSHIPS Filed 'A'u e, 1925' 2 Sheets-Sheet 2 Patented July 28;," 1931 f mooRING MAsm FOR Amsnirs' This invention relates to mooring masts for airships and has for itsobject to provide a I new and improved device of this description.

The invention has as a further object toprovide a mooring mast for .dirigible flying machine's with means assooiatedjtherewith to which the airship may be connected and 5 which is movable longitudinally along. the

stationary portion of the mast.

I The invention has as a p i provide a mooring mast with an elevated platform with which the dirigible 1s connected and which is movable up and down along the stationary portion" of the device. I s

The invention has further objectswhlch are more particularly pointed out in the accompanying description. j Referring now to th drawings:

withstand the pull "of the airship and the other stresses that come thereon.

In" the construction illustrated this tower 1 is rectangular in form and is provided with the corner uprightmembers 2, 3, 4 and 5 con nected'together by a series of cross members I 6, 7 8 and 9 located at different points along the upright members and these cross members are lacedtogether by suitable connecting members, the whole being'preferably arranged to form a trussconstr'uction. This structure therefore forms a self supporting tower ormast. i i I 7 An elevating: platform "10 3 is connected with the tower .1 and is arranged to be moved further object to up and down therealong. This elevating platform ispreferablycircular in shape and isprovided'with rollers 11 and 12'which roll. 1

ing device 16 to whicha'the airship-is con nected. The airship. is provided-with an at! taohing device consistingof themember 1'7 having pivoted thereto the member '18. The member 18 is preferably cone shaped and the opening inthe fastening device 16 is alsoicon'e shaped 2toreceive the member 18. The main hauling line l9ris connected with theinember' 18 of ithe' attaching device: and thetwo 'parts JosErH B. s'rnnnss, oF-onioAqo, infmors Connected [with the elevating platform may be connected-together by thefa'stenerI'QO.

2 The elevating platform f 10 is moved up n and [down {along the-"tower by any suitable means. As herein-shown, this is: done meansof f7cable s-21. These'cables pass over pulleys 212113 the top of the tower and about drums 23 at the bottom" of the tower, ithus forming "loops, one member of eachloop be ,ing connected with the elevating platform 10. s

"Some means is' provided for rotating the drums 23. herein shown, these drums are rotated-by a shaft 24 connected tothe drums byisuitable gearing,-the shaft beingrotated b'yamotor 25. p A'second platform 26*may be provided.

This platform'may be similar to platform 10 except that it'does not have the rotating ring 14.'6This platform may be used 'for 'carrying passengers up to and down from the airship, and forloading and unloading passengers. The! platform 26 is providediwith means, for

preventing the platform 10 fromapproach ing near enough to "injurethe passengers. 7 This may be accomplished by having posts on the platform 26 which are engaged by the platformlO when the two platforms come together and which are'of sufficient height to prevent the passengers from being injured.

The platform 26 may be lifted andlowered by amechanism similar to that for platform 10. There is illustrated for this pur-.

' pose cables27 which pass over pulleys 28 at the top'ofthe tower' and drums 29 at the bottom of the tower, the drums being rotated by the shaft 30 connected with the motor 31,

n there being the necessary-redueing gears be tween the motor and the drums. j
